Wooden Electronic Ruler Will Make You Want to Measure Stuff

Designer Shay Shafranek’s concept for an electronic ruler manages to retain the familiar look of the analog instrument while making it easier to use.

Using the electronic ruler is as simple as using its analog ancestor. Press the power/reset button on the ruler and the LEDs light up, waiting for your input. The wooden cover conceals what the pencil in the image above is touching: a line of metal points jutting out from the inner edge of the ruler. The ruler uses the change in voltage induced by touching one of these points to calculate the distance.

Because of the LEDs and the ruler’s memory, you don’t have to memorize the length or distance of what you’re measuring even if it’s beyond the ruler’s length because the recorded length stays displayed as long as you don’t press the reset button.The ruler can also be set to remember a relative zero point; just touch the point you wish to be recognized as zero as soon as you press the reset button. And if you touch two points while pressing the reset button, the ruler will use the distance between those two points as one unit.

The functions and ease of use of Shafranek’s concept are certainly noteworthy, but I think its the wooden cover that really makes the electronic ruler awesome. I hope someone helps mass produce this. Check out Shafranek’s website for more details.

hello
first I want to thank you about your brilliant idea for this ruler.
and after that I want to know is it posible for you to send me the circuit of this ruler?
I want to try it my self.
I live in IRAN and I though about produce it in IRAN and make a carear out of it.

Hi zarezadeh, as I mentioned in the article, I’m not the one who came up with this idea. If you really want to know more about the ruler, I suggest you visit the designer’s website and see if there are contact details there.
